I have a list of several thousand file paths in /tmp/files. Write a python script that merges the content int 16 files called /tmp/merged_%d for i in 0..15 where each is approximately the same size. "/tmp/files" is a list of file paths, one per line.
To achieve the task of merging the content of several thousand file paths listed in `/tmp/files` into 16 approximately equally sized files named `/tmp/merged_%d` (for `i` in 0..15), you can follow the steps outlined in this Python script: 1. Read the file paths from `/tmp/files`. 2. Calculate the total size of all files to determine the approximate size each of the 16 files should be. 3. Iterate through the file paths, reading their content and writing it to one of the 16 output files in a way that balances the total size across these files. Here is a script that does this:

To achieve the task of merging several thousand files into 16 approximately equally sized files, you can follow the approach outlined below. This script involves reading the list of file paths from `/tmp/files`, calculating the total size to aim for equal distribution, and then merging the content into 16 files named `/tmp/merged_%d` where `%d` is in the range from 0 to 15. Note: This solution assumes that the size of the content of these files can fit into memory reasonably well. If the files are very large, you might need to adjust the approach to handle memory more efficiently.

This script reads the list of file paths, calculates the approximate number of files that should go into each merged file to balance their sizes, and then writes the contents into the respective merged files.

I have setup the docker container to run the model evaluation.
I have a list of several thousand file paths in /tmp/files. Write a python script that merges the content int 16 files called /tmp/merged_%d for i in 0..15 where each is approximately the same size. "/tmp/files" is a list of file paths, one per line.
I have a list of several thousand file paths in /tmp/files. Write a python script that merges the content int 16 files called /tmp/merged_%d for i in 0..15 where each is approximately the same size. "/tmp/files" is a list of file paths, one per line.
To accomplish this task, you can follow these steps in your Python script: 1. Read the list of file paths from `/tmp/files`. 2. Calculate the total size of all files to distribute them evenly. 3. Open 16 output files for writing. 4. Iterate through each file path, read its content, and write it to one of the output files in a round-robin fashion or based on size constraints. 5. Close all files. Here's a basic implementation to get you started. This script aims to balance the output files by size as evenly as possible. Note that this approach assumes that individual file sizes are not significantly larger than the total size divided by 16, as that could lead to less optimal distribution.

I extracted the following code from that output:
